Answer 1

分析 文章講述了校園暴力．選擇校園暴力引起了廣泛關(guān)注，我們要想方設(shè)法避免它的發(fā)生．遇到校園暴力時(shí)，要及時(shí)和父母老師溝通，不能以暴制暴．

解答 答案：61．exist；考查動(dòng)詞．句中did是對(duì)謂語動(dòng)詞的強(qiáng)調(diào)，后面要用動(dòng)詞原型．   
62．Obviously；考查副詞．句中obvious修飾整個(gè)句子內(nèi)容，要用副詞形式．  
63．a(chǎn)；考查冠詞．句意表達(dá)的是泛指，要用不定冠詞來限定．    
64．which/that；考查連詞．句中calls for our great concern修飾phenomenon，是一個(gè)定語從句；從句缺少主語，且先行詞phenomenon指物，要用which或that來引導(dǎo)． 
65 happening；考查動(dòng)名詞．句中happen作介詞from的賓語，要用動(dòng)名詞形式．
66．if；考查連詞．句意表達(dá)的是假設(shè)，要用if來連接條件狀語從句．  
67．be learned/learnt；考查語態(tài)．句中l(wèi)earn與主語violence構(gòu)成動(dòng)賓關(guān)系，要用被動(dòng)語態(tài)；learn的過去分詞既可以是規(guī)則變化，也可以是不規(guī)則變化． 
68．what；考查連詞．句中they see on television or on the Internet作介詞from的賓語，是一個(gè)賓語從句；從句缺少賓語，且句意表達(dá)的是事情，要用what來連接．   
69．with；考查介詞．句意表達(dá)的是用某種工具，要用with來表示；answer violence with violence以暴制暴． 
70．should/ought to/must；考查情態(tài)動(dòng)詞．句意表達(dá)的是建議，每個(gè)學(xué)生應(yīng)該注意言行，遠(yuǎn)離暴力．

點(diǎn)評(píng) 語法填空題是考查學(xué)生的語言運(yùn)用能力．解題時(shí)，要在理解文章的基礎(chǔ)上，靈活運(yùn)用語法知識(shí)，如詞性，時(shí)態(tài)，名詞單復(fù)數(shù)，連接詞，代詞，冠詞等判斷空白處應(yīng)填寫的內(nèi)容．答完后，還要通讀全文，核對(duì)所填單詞形式是否正確，是否符合語境．
